DETAILED DESCRIPTION

Safety of children and animals near fire is of paramount importance to people who enjoy outdoor recreational fires. Accordingly, the disclosed device is designed to protect small children and pets from burns that may occur from accidental close proximity or contact with these fires. However, this device allows individuals to enjoy the ambiance of an outdoor fire while still maintaining a protective barrier that does not otherwise significantly detract from the viewing and use of the fire.

Reference is now made to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding thereof. It may be evident, however, that the novel embodiments can be practiced without these specific details. In other instances, well known structures and devices are shown in block diagram form in order to facilitate a description thereof. The intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the claimed subject matter. The invention relates generally to a portable barrier device that protects children and animals from accidental contact with campfires.

Referring initially to the drawings, FIGS. 1 and 2 illustrate a barrier device 100 for use with an outdoor recreational fire 180. The barrier device 100 comprises a plurality of gate panels 102 and a plurality of hinge elements 118. Unless otherwise stated, the components of the barrier device 100 are preferably constructed of wood, glue, iron and poly vinyl chloride, though it is contemplated that other suitable materials, including without limitation steel, aluminum, metal alloys, polymers, wood products, and the like, can be used without affecting the overall concept of the invention. Further, any of the construction materials used may also be coated with a fire resistant high temperature paint or coating.

When in use around a fire, the barrier device 100 is substantially polygonal in shape and preferably comprises a seven-sided heptagon. The preferred size provides an enclosure with an approximate diameter of between 68 and 70 inches, and an approximate circumference of between 200 and 230 inches. These dimensions allow for adequate protection for a fire or fire ring of between 10 and 30 inches in diameter while maintaining a distance of between 15 and 30 inches from any point in the base of the fire. However, this is not meant as a limitation as the barrier device 100 dimensions may be smaller or larger as desired. For example, a larger barrier device 100 may be desirable for bonfires to ensure an adequate protective distance. When not in use, the barrier device 100 easily collapses or folds along the plurality of hinge elements 118 to the approximate dimensions of one of the plurality of gate panels 102, as discussed infra, and to between seven to nine inches in depth. When in the folded or un-deployed position, the plurality of gate panels 102 align in a substantially parallel orientation. As the barrier device 100 preferably weighs between 15 and 35 pounds, and is simple to fold and/or unfold, it is easily portable.

Preferably, the plurality of gate panels 102 are manufactured from wood or a wood product, however, as discussed supra, this is not meant as a limitation as a wide variety of common construction materials may be used with out affecting the overall concept of the invention. Similarly, the wood is preferably coated with a fire resistant paint or coating to protect the wood from degradation and combustion. For example, the wood may be sprayed with a high temperature acrylic based paint such as those used to coat stoves, grills, automotive parts, and the like. In addition to protecting the plurality of gate panels 102 from combustion, the coating acts as an insulator to keep the wood or other construction material from becoming hot enough to cause a burn injury from contact.

Each of the plurality of gate panels 102 further comprises a top rail 104, a bottom rail 106, and a plurality of pickets 116. Referring to FIGS. 2, 3, and 3A, the top and bottom rails 104 and 106 respectively, both comprise an offset portion 108 and an arm portion 114 with a total preferred combined length of 32 inches. The offset portion 108 typically is two inches wide extending perpendicularly about one and a half to two inches before angling approximately 45 degrees back into the arm portion 114. However, any angle between zero and 90 degrees, and any geometric or ornamental design that extends the width of the offset portion 108 is acceptable and still within the scope of the invention. Both the offset portion 108 and a distal end of the arm portion 114 of the top rail 104 further comprise a top through hole 110, and the offset portion 108 and a distal end of the arm portion 114 of the bottom rail 106 further comprise a bottom through hole 112. The top and bottom through holes 110 and 112 are approximately centered in the corresponding offset portion 108 and the distal end of the arm portion 114 and are between ¼^(th) and ½ inches, but preferably ⅜^(th) of an inch in diameter.

The plurality of pickets 116 are generally round, however, any ornamental design or geometric shape such as square, rectangular, hexagonal, and the like, will not deviate from the scope of the invention. Typically the plurality of pickets 116 are ½ inches in diameter and 24 inches in length. But as discussed supra, these dimensions are not meant as a limitation on the scope of the invention. Preferably, six of the plurality of pickets 116 are set vertically between the top and bottom rails 104 and 106 of each of the plurality of gate panels 102 so that the plurality of pickets 116 are approximately equidistant at about four inch intervals. The four inch interval is beneficial in that it is close enough so that a child or pet may not fit between the plurality of pickets 116, but still allows for a mostly unobstructed view of the fire. However, any number of pickets may be used and not vary from the scope of the invention.

The plurality of pickets 116 are typically centered in the top and bottom rails, 104 and 106, and set into a plurality of non-through holes 160 approximately ½ inches deep into the underside of top rail 104 and the top side of the bottom rail 106 as seen in FIG. 3A. The plurality of pickets 116 are further attached with glue and brads. However, any known method of attaching wood elements, including adhesives, mechanical fasteners, and joints is considered equivalent.

While the plurality of gate panels 102 typically number seven, the barrier device 100 may comprise a greater or lesser number as desired and still be within the scope of the invention. Each of the plurality of gate panels 102 preferably are approximately 25 inches high, although this is not meant as a limitation on the scope of the invention as the height may range from 18 to 36 inches. However, the 25 inch height permits a substantial barrier for small children and pets while still allowing for easy access to the recreational fire 180.

As shown in FIGS. 2, 2A and 2B, the plurality of gate panels 102 are rotatably connected by the plurality of hinge elements 118 so that a first adjacent gate panel 102(a) is connected to a second adjacent gate panel 102(b). A plurality of fixedly attached connecting elements 120 are inserted into the plurality of hinge elements 118 so that the plurality of gate panels 102 may rotate about the plurality of hinge elements 118. The plurality of fixedly attached connecting elements 120 comprise a rod element 122. The rod element 122 is typically a 5/16^(th) diameter iron or steel bar, however any metal, metal alloy, wood, plastic, and the like of diameters ranging from ¼^(th) to ½ inches may be used and still be within the scope of the invention. The diameter of the rod element 122 is only limited by the diameter of the through holes 110 and 112. The rod element 122 is inserted through the top and bottom through holes 110 and 112 of the offset portion 108 of the first adjacent panel 102(a) and the top and bottom through holes 110 and 112 of the distal end of the arm portion 114 of the second adjacent gate panel 102(b) thereby connecting them.

The rod element 122 comprises a top cap element 124 of a greater diameter than that of the through holes 110 and 112 that is welded or otherwise fixedly attached and a top washer 126 that freely spins. Both the top cap element 124 and the top washer 126 are positioned above the top rail 104. The rod element 122 further comprises at least one bottom washer 130 that freely spins, a crimped element 132, and a spike portion 134. The at least one bottom washer 126 is positioned below the bottom rail 106 and is held in place on the rod element 122 by the crimped element 132 which is compressibly attached below the at least one bottom washer 126 fixing the rod element 122 in place in the plurality of hinge elements 118. Preferably, there are two bottom washers 130 (according to FIG. 2B). The rod element 122 terminates in the spike portion 134 of between six to ten inches in length which is insertable into the ground up to six inches in depth.

Additionally, the rod element 122 is partially encapsulated by a center sleeve element 128 positioned between the top and bottom rails 104 and 106. The center sleeve element 128 is preferably a length of poly vinyl chloride pipe coated with a fire resistant paint, as discussed supra, however any similar material known to one of skill in the art is considered within the scope of the invention. The center sleeve element 128 serves as an insulator so that the iron or steel rod element 122 does not become hot enough to burn a person or animal. To deploy or collapse the barrier device 100, as shown in FIGS. 1 and 5, the user may move the plurality of gate panels 102 which are horizontally disposed into a desired polygonal orientation around the fire or into a folded storage position by simply rotating the plurality of gate panels 102 about the plurality of hinge elements 118 in the desired direction.

Referring to FIG. 4, a fastening element 138 is employed to selectively connect an outer two of the plurality of gate panels 102 so that the barrier device 100 forms a polygon-shaped configuration, such as a heptagon, when connected. Furthermore, additional gate panels (not shown) may be added to the barrier device 100 to create a larger polygon. The fastening element 138 comprises a fixed element 140. The fixed element 140 is preferably a metal rod similar to the rod element 122 discussed supra. Like the rod element 122, the fixed element 140 further comprises a spike 142 and a center sleeve 144. However, the fixed element 140 further comprises a top securing element 146 and a bottom securing element 150. The top and bottom securing elements 146 and 150 preferably are L-shaped hooks extending from the body of the fixed element 140 with the bottom securing element preferably longer in height than the top securing element 146. However, other securing connectors known to one of skill in the art such as straps or flexible tubing are acceptable as well.

The barrier device 100 forms a fire enclosure when a first outer gate panel 102(c) is connected to a second outer gate panel 102(d) with the fastening element 138. The first outer gate panel 102(c) employs the fixed element 140 positioned between the top and bottom through holes 110 and 112 to form an outer hinge element 118(a). Next, the second outer gate panel 102(d) is moved adjacent to the first outer gate panel 102(c). From underneath, the bottom securing element 150 is placed through the bottom through hole 112 of the first outer gate panel 102(c) so that the first and second outer gate panels 102(c) and (d) are engaged at the bottom. Simultaneously, the top securing element 146 is positioned so that it may slide up through the top through hole 110 of the first outer gate panel 102(c) so that the first and second outer gate panels 102(c) and (d) are engaged at the top as well. The top securing element 146 is then held in place with a locking element 148 so that the first and second outer gate panels 102(c) and (d) stay connected. The locking element 148 may be a cotter pin for example, or of any other temporary attaching element known to one of skill in the art.

Returning to FIG. 1, the connected barrier device 100 is positioned around the fire 180 so that it is completely surrounded. The barrier device 100 is further stabilized by stepping on the bottom rail 106 of the plurality of gate panels 102, or alternatively by using a hammer to drive the rod elements 122 and the fixed element 138 in to the ground. The spike portion 134 and the spike 142 are driven into the ground so that the bottom rails 106 are positioned between two to six but preferably four inches above the ground to prevent access underneath the barrier device 100. The barrier device 100 is removed by pulling it out of the ground, disengaging the fastening element 138, and folding for storage.

What has been described above includes examples of the disclosed device. It is, of course, not possible to describe every conceivable combination of components and/or methodologies, but one of ordinary skill in the art may recognize that many further combinations and permutations are possible. Accordingly, the novel device is intended to embrace all such alterations, modifications and variations that fall within the spirit and scope of the appended claims. Furthermore, to the extent that the term “includes” is used in either the detailed description or the claims, such term is intended to be inclusive in a manner similar to the term “comprising” as “comprising” is interpreted when employed as a transitional word in a claim.
